At present, countries around the world are actively exploring the ideas and directions of carbon emission reduction, and as China’s economy gradually shifts to a high-quality green development stage, the carbon reduction strategy has also become the general starting point of the “14th Five-Year Plan” for ecological and environmental protection, providing a low-carbon Transformation draws a general roadmap.
ABB has been deploying future-oriented net-zero carbon and low-energy buildings for a long time. In the Chengdu Tianfu International Airport project, the largest domestic civil hub airport planned and constructed in China’s “13th Five-Year Plan”, ABB has provided electrical solutions and intelligent building control systems by providing electrical solutions and intelligent building control systems. Scientific management and effective energy saving can ensure the comfort of passengers while reducing the energy consumption of the airport, helping Tianfu International Airport to be rated as a three-star green building in China. As stated in the “ABB Electric Carbon Neutrality White Paper” (referred to as the “White Paper”), in the future, ABB will make full use of the leading solutions of electrification, digitization and intelligence, and learn from the experience and achievements of global green transformation to accelerate the improvement of quality and efficiency of the construction industry. Upgrade.
Based on full life cycle analysis,
The key to building net-zero emissions
Data shows that the construction industry consumes more than 30% of the world’s energy and accounts for nearly 40% of global energy and process-related carbon dioxide emissions. At the same time, China is also the country with the largest number of existing buildings and new buildings each year in the world. According to the “China Building Energy Consumption Research Report (2020)”, the total carbon emissions in the whole process of construction in 2018 was 4.93 billion tons, accounting for 4.93 billion tons of carbon emissions in the country. 51.3% of the proportion of emissions. Therefore, it is imperative to realize the green and low-carbon development of buildings.
At the same time, the “Carbon Peaking Action Plan before 2030” issued by the State Council in October 2021 pointed out the general direction for how to achieve green and low carbon in the construction industry, that is, to accelerate the optimization of building energy structure, accelerate the improvement of building energy efficiency and comprehensively improve energy conservation management ability. Specifically, in the process of my country’s gradual entry into a new stage of urbanization, throughout the entire life cycle of the building industry chain, compared with the carbon emissions of building construction, the proportion of carbon emissions in the building operation stage is increasing year by year.
The “White Paper” further pointed out that in the process of building operation, the energy consumption of HVAC systems and lighting systems accounts for nearly 50% to 70%. and goals are paramount. Since most of the energy that drives buildings is still fossil energy, and the proportion of renewable energy is only about 6%, building more clean energy and achieving maximum consumption will become the best way to reduce carbon emissions in the construction industry.
Focus on three paths,
ABB delivers on its commitment to carbon neutrality in the construction industry
Breakthrough and innovative technologies are the key to enabling buildings to move towards carbon neutrality. ABB has successively launched ABB Mission to Zero™ projects around the world. Through technologies such as ABB Ability™ digital and smart energy management solutions, Actively implement the commitment to promote carbon emission reduction in the construction industry. The “White Paper” analyzes how to solve the contradictions and challenges of the whole chain of building energy supply and demand from the three dimensions of energy supply, energy consumption, and operation management, so as to provide a guarantee for the safe, stable and efficient use of clean energy in buildings, and to help buildings continuously optimize the user experience. On the basis of this, the overall energy demand and carbon emissions can be reduced.
- Optimizing the energy mix and energy management of buildings
At the beginning of March, it was mentioned in the “14th Five-Year Plan for Housing and Urban-Rural Construction Science and Technology Development Plan” issued by the Ministry of Housing and Urban-Rural Development that it is necessary to develop high-efficiency smart photovoltaics based on accurate forecasting of building user loads and regional building energy efficiency improvement technologies that complement each other. Clean energy utilization schemes such as building integration (BIPV) and power system “photovoltaic, storage, direct and flexible” will become an active practice in optimizing the energy structure.
With the help of ABB’s photovoltaic building integration technology, users can easily access new energy facilities such as rooftop photovoltaics to improve the building’s own clean energy production capacity. At the same time, ABB brings forward-looking DC power distribution technology for future buildings, helping users to easily deploy distributed energy, energy storage, and access to DC loads and variable-frequency AC loads, eliminating some AC-DC conversion devices. At the same time, the DC microgrid can also be interconnected with the existing AC microgrid or distribution network to form a multi-source support, which greatly increases the flexibility of electricity consumption, greatly optimizes the building energy structure and improves energy efficiency.
In addition, the asynchronous problem of supply side and demand side is the key node of building photovoltaic consumption problem. ABB’s smart energy management system can perform flexible multi-strategy regulation of “source-grid-load-storage-end”, and allocate clean energy, energy storage and adjustable loads according to clean energy power generation, environmental factors, electricity tariffs, load conditions, etc. , to realize the “virtual power plant” management and “source-load interaction” of the building body in the form of energy release and energy storage. During peak hours and when the supply of clean energy is tight, the usage time can be flexibly adjusted according to the actual power generation status of photovoltaics and adjustable load attributes, so as to achieve energy supply and orderly electricity consumption inside the building, and achieve a tight balance between supply and demand of clean energy.
